The fourth round of the World Cup of Boulder sport climbing was held in the Czech Republic, and in the women's competition, Tokyo Olympic silver medalist Moe Nonaka finished fourth in the Japan and Futaba Ito finished sixth.

Sport climbing boulder is an event called "challenge" in which participants compete to see how many times they have climbed a course within a time limit.

The fourth match of the World Cup season took place in Prague, Czech Republic on 4 September Japan, with 4-year-old Nonaka and 26-year-old Futaba Ito advancing to the six-man final.

Nonaka had the first task and made dynamic moves that made the most of the power of his taste to complete the climb with a "blow" that he climbed on the first try, and although he could not climb the second task, he reached a point called the "zone" in the middle of the course.

In the third challenge, he struggled and could not reach the zone, and in the fourth and final challenge, he put one hand on the top hold but could not hold it with both hands, so he was not allowed to complete the climb and finished fourth.

Nonaka said, "I knew that if I could score the final task, I would win a medal, so I was aiming for it.

Ito reached the zone in two of the four challenges, but was unable to climb and finished sixth.

The winner was 21-year-old Orianne Berton of France.
